As shown in the drawings, 1 is a suitable supporting pedestal having aplate or table 2 upon which two like supporting frames 3 arc secured,said frames being provided with bearings for a transverse driving shaft4. a counter shaft 5 and a cam shaft 6. Mounted upon one end of thedriving shaft 4 to turn freely thereon, is a belt pulley T having aninternal clutch face adapted to be engaged by a cone clutch wheel 8mounted upon the shaft to slide longitudinally thereof and operativelyconnected thereto to turn therewith. A spring 9 (sec Fig. 1T) interposedbetween the pulley and wheel normally holds the clutch inoperative. andto move said clutch wheel into engagement with the pulley against theaction of said spring. a har 1U is guided to move longitudinally in avertical position by n slot therein through which the shaft 4 extend.-and h v n forked upper end embracing the shaft (i. A\n outwardlyprojecting portion 11 on .said har around the upper ends of said slottherein for the shaft 4, has an inclined or earn face to engage asimilarly' formed face upon one end of a collar 12 on the shaftinterposed between said bar 10 and the adjacent end of the hub of thewipers and showing the stops section ,through the stop mechanism; 18, aside elevation of the stop mechaof the clutch wheel. A pin 13 on the barengages a slot in a downwardly extending lug on the collar to hold saidcollar from turning upon the shaft and a coiled spring 14 attached atone end to the bar and at its opposite end to the frame 3, normallyholds the bar raised, the bar being moved downward against the action ofsaid spring to bring its cam proi'ection 11 into engagement with the colar and force the same outwardly to move the clutch wheel into operativeposition, by a rod 15 pivotally at tached to its lower end which rod maybe operated in any suitable manner, as bya foot pedal (not shown). Themachine will be driven by the belt pulley 7 as long as "the bar 10 isheld lowered and will stop immediately upon the release of said bar andthe raising of the same by its spring 14.

To insure the stopping of the machine with its parts in certainpositions and to hold the same in the position in which. they arestopped, a disk or stop plate 16 is secured upon the end of the camshaft 6 outside of the bar 10. This disk 1s formed with any desirednumber of notches 17 in its periphery adapted to be engaged by a 4roller stud 18 on the bar 10 when said bar is released by the operator.Those notches are so positioned relative to cams, herein` afterdescribed, secured upon the cam shaft, that upon release of the bar 10,the roller stud, riding upon the periphery of said disk will drop intoone of said notches and positively stop and lock the cam shaft with theparts of the mechanism operated'by the cams, in exactly the desiredposition. Any desired number of these notches may be provided to stopthe machine at any desired point Ain the revolution of its cam shaft,and if the operator wishes a continuous operation of the machine, it isonly necessary that he hold the bar to prevent the roll from engagingthe notches.

Motion is transmitted from the driving shaft 4 to the counter-shaft 5 bygears 19 and from the countershaft to the cam shaft 6 by gears 20, thespeed being reduced thereby to drive the cam shaft at a slow speed.

Secured to the frames 3 at their forward side is a bracket 21 having alongitudinal opening therethrough to receive a bar 22 which is square incross-section where it passes through said bracket and is free to slidelongitudinally therein. A rear end portion of the bar is also formedsquare in cross section to slide in a bearing therefor in a member 23extending'across between the frames, and the bar is preferably made intivo parts connected by a coupling sleeve 24 engaging the adjacentscrewthreaded ends of the two parts and servin as a turn buckle by meansof which the e ective length of the bar may be the groove. As shown inFig. 24, ortions of said groove are wider than the iameter of theroller, and thus when said roller is in those portions of the groove,the bar may be moved rearwardly a short distance against the action ofsaid spring 27.

Mounted upon the rounded forward end of the ush bar 22 to turn thereonis a head 29 hel in place upon the bar by a pin 30 fast in the bar andengagin a transverse slot in the head. Laterally extending anges 31 onthe head form between them a transverse horizontally extending andforwardly open slot to receive wiper-carrying plates 32 which carryingplates are in turn formed in their forward edge with a slot to receivewiper plates 33. These wiper plates are pivotally connected by a pin 34and are provided with the usual formed forward edge to engage the heelor toe of a boot or shoe, wiper plates having an edge formed accordingto the work to be done and approximating the outline of the heel or toeof the last, being placed in the slots of the carrier plates 32 andsecured therein to move therewith, by pins 35. The formed edge of theWiper plates is beveled in the usual manner and the adjacent curvededges of the carrier plates are also beveled so as not to hinder theoperation of the other parts of the machine. The carrier plates 32 areheld within the slot in the carrier head 29 formed between the flangesthereon, b pins 36 secured in the anges and provided with roller sleevesen aging curved slots 37 in the plates. These s ots are curvedconcentrically with the axis of the pivot 34 of the wiper plates so thatsaid carrier plates may turn freely to open and close the wiper plates,and to so actuate the carrier plates, each is provided with a laterallyextending lug having a vertical opening to receive the shank of an eyebolt 38 which turns freely therein and is provided with a horizontallyextending screwthreaded opening in its head to receive a screwthreadedrod 39. Each rod is formed with an enlarged rear end (see Figs. 4 and 5)forming a shoulder 40 and is provided with a head 41 to engage the headof an eye bolt 424 and slide freely through the heads of the eyebolts,thus providing a universal joint connection between the rear ends ofsaid rods 39 and said cross bar.

A milled head 44 is secured to the forward end of each rod 39 by meansof which the rod may be turned to adjust the same through the eyebolt38, and a heavy coiled spring 45 is sleeved on the rod between anadjustable collar 46 having screwthreaded engagement with the rod and acollar 47 free to slide longitudinally on the rod and normally held bysaid spring in engagement with the shoulder 40. The collar 47 isexternally screw-threaded to receive an internally screwthreaded sleevemember 48 and a second coiled spring 49 which is of y considerably lessstrength than the spring 45, is sleeved upon the enlarged portion of therod between said sleeve 48 and the eyebolt 42 through which said portionof the rod is adapted to slide.

A push bar 50 having a forked head 51 connected to the forward end ofthe bar to rotate freely thereon (see Figs. 5 and 8) embraces the crossbar 43 and is pivotally attached to said cross bar intermediate the endsthereof, by a bolt passing through said forked end and bar, and a Hatspring 52 secured to said bar 50 intermediate its ends engages the crossbar at its ends to normally hold said cross bar in a positionsubstantially at right angles to the push bar. The push bar ispreferably made adjustable in length by forming the same in two partshaving screwthreaded adjacent ends t0 engage a coupling sleeve or turnbuckle 53, aud upon the rear end of said push bar is a roller 54 toengage a cam groove in a cam wheel 55 secured upon the cam shaft 6.

ln this construction, the wipers are rigidly supported against verticalmovement h v the carrier head 29 and are given a forward and rearwardmovement by the longitudinal movement of the push bar 22 .slidingthrough the supporting bracket 21. Said push har is yieldingly held inits forward position by the spring 27. the cam groove on the cam 26being wider than the diameter of the roller on the bar t0 permit the harto move a limited distance rearwa rdly independently of the cam which0perates to move the wipers rearwardly against the action of saidspring. The wipers are thus vieldingly forced longitudinall) intoengagement with the heel or toe of a last when the roller is in the wideportions of the earn and are positively mined rearwardly when saidroller is in those portions of the cam slot which fit the roller. Thewipers are therefore yieldingly pressed against the end of the shoe whenmoved into engagement therewith and variations in the thicknesses of theleather at the point of the toe or heel of different boots or shoesoperated upon, is thus rovided for by the spring 27 which will yieldwhen a resistance due to the increased thickness of the leather, isoffered which is greater than the tension of the spring, said tensionbeing decreased or increased by means of the adjustable collar 28 togive the desired wiping effect. a The wiper closing cam 55 is so set inrelation to the wiper retiprocating cam 26 that the wipers will beclosed upon the heel or toe of the last as seen as they are movedforwardly, and owing to the interposition of the springs 49 between theeyebolts 42 and the sleeves 48, they will be yieldingly closed, saidsprings yielding and permitting the rods to move through the eyebolts.Ytl'hen the resistance to the closing of the wim-rs is sufficient, thesprings 4!) will he fully compressed or closed, and further pressurewill then come upon the springs 45 which are of such strength that theywill yield only after the closing of the springs 49, the collar 47 andsleeve 48 being forced to slide longitudinally of the rod against theaction of the spring 45 by the pressure of the eyebolts 42 upon theclosed springs. The wipers are thus closed hy a varying spring pressureupon the work, the springs 4t* forcing the wipers inwardly against theshoe upper below the sole with a comparatively light yielding pressure,and the springs 45 closing the wipers over the edges of the shoe solewith a heavy yielding pressure. The equalizing bar 43 and the jointedconnection between it and the carrier plates 32. permit said wiperplates to freely adjust themselves to the work, said carrier platesturning together or independently of each other about the common centerof the wiper plates to conform to the swing of the last, and saidequalizing bar also serves to equalize the pressure of the wipers uponthe sides of the heel or toe, thus providing for differences in thethickness of the leather at the two sides of the shoe and givingtogether with the yielding forward movement of the wipers an even smoothyielding wiping action all around the toe or heel of the shoe. Y

In Fig. 1S) a modification in the closing mechanism for theWiper-carrying plates is shown. Solid straight externally screwthreadedrods 92 engage the eyeholts 38 near their forward ends and at the rearends eX- tend through the eyebolts 42 to turn freely therein. Said rodsare held against longitudinal movement through the eyebolts 42 byrzeant; of collars 93 and nuts 94 on the rods engaging the heads of saideyebolts. These rods thus form unyielding connections between thecarrier plates' and the ends of the equaliziner bar so that said plateswill be positiveliY moved when the puslrbar 50 is actuated by thecan1-whee1 95 shown in Fig.

20. In the operation of a machineeinbodying this construction, after thewipers have been moved bodily forward by the cam 26, they are closedupon the heel or toe of the last by turning the rods 92 by hand, and aregiven a closing movement to proJect them over the edge of the sole andform down the shoe upper by the cam 95 which is arranged to close thewipers positively a fixed distance each time, thus obviating theliability of the wipers being pro ected too far over the edges of thelast an destroying the shoulder of an insole thereon.

The downward pressure of the Wiper lates upon the wor along each side ofthe ast, is equalized as said plates are forced over the edges of theshoe sole upon the last to form the edge of the shoe upper down hardthereon, by the free turnin of the wi er head 29 upon its bar 22, saiturning bein limited by the pin 30 in its slot and also y shoulders 56(see Fig. 7) formed on the bracket 21 at each side thereof ada ted to been aged b a projecting ortion o the head. hen the leather is t icker atone side of the last than at the other, as for instance, when the upperand box are misplaced upon the last as illustrated in Fig. 13, the headwill tilt, conforming to the differences in thickness of the leather atthe two sides of the shoe, and thus the two edges of the last will besubjected to the saine pressure, and injury tothe shoe or undue strainupon the wipers and their support will be avoided. Y

When the Wiper head is moved rearwardly, bringing the wipers into inoerative position for the discharge of the ast and the reception ofanother. the head, provided it has been tilted during the lastoperation, is again brought into a horizontal position by a spring arm57 (Figs. 4 and 7) secured at one end to the bracket 21 and engagingnear its opposite end an eyebolt 58 carried by the head 29. The wipersare thus yieldingly held in the proper horizontal position to engage alast.

The last with a boot or shoe thereon, is supported from below inposition for lastin by a jack comprising a verticall movab e post 59provided with a detachab e head 60 and guided in guide bearin on a frame61 guided to slide vertically in guidewa s on `a supporting bracket 62secured to the forward edge of the table 2. The lower guide bearing forthe post is internally screwthreaded to receive an externallyscrewthreaded sleeve 63 on the post, and between the u per end of thissleeve and a collar 64 ad]ustably secured upon the post is a coiledspring 65 sleeved upon the post. The height of the post is regulated bythe position of the col ar 64 which abuts the upper guide bearing forthe post and limits i upward movement. The post is thus `rod, and whic66 pivoted at 67 upon downwardly extending arms on the frames 3, theforward end of said lever being connected by a link 68 to the verticallysliding frame 61. The rear end of the lever is curved and extendedupwardly and provided with a roller 69 at its extreme end to engage theperiphery of a cam 70 secured upon the cam shaft 6. The lever 66 is heldturned with its roller in engagement with the cam by means of a sprinsaid ever. Y

When in place within the machine, the last is clamped between the jackat the lower side and a hold-down 72 engaging the shoe sole upon thelast at about the lon tudinal center line of the last, said ho ddownbeing oval shape in plan view and provided with sharp projections orteeth on its under side to engage the sole. This hold-down is attachedto the lower end of a post 73 which is adjustably held within an openingin the forward end of a lever 74, by

a set screw 75. The lever 74 is U-shape in y plan view, its two sidearms being pivoted to the two frames 3 at 76 and one of said arms beingextended rearwardly. To this rearwardly extending end 77 of the lever isivotally attached a tail piece 78 having a orked portion embracing saidend and provided with a roller 79 on its downwardly curved end to engagea cam 80. The rock lever is held turned with said roller in contact withthe cam, by a coiled spring 81 attached at its lower end to a cross baron the frames 3 and at its upper end to the rear end of an extension bar82 secured to the arm 77 of the lever. The tail piece 78 is turned uponits pivot to adjust the same relative to the rock-bar and yieldinglyheld in its adjusted position by providing a screw threaded opening inthe arm 77 to receive a screw threaded rod 83 (Fig. 16) which isprovided with a hand wheel 84 upon its u per end for turning said rodextends downwardly through an o enin in a cross-bar 85 connectin thesides o the forked end of the tail piece 78 beneath said arm 77. A fixedcollar 86 on the rod engages the upper side of said cross-bar and a cap87 sleeved on the rod is held in contact with its lower side by a coileds ring 88 sleeved on an enlarged lower end o the rod with its lower endin enga ement with a nut 89 thereon, which nut may e turned to changethe tension of said spring. The enlarged ortion of the rod fits and isadapted to s 'de within an en- 71 attached to the forward end of largedend of the bore of the cap which enlargement of the bore forms aninternal shoulder 90 on the cap to oppose a similar shoulder 91 formedon the rod by said enlargement.

lVhen the lever 74 is rocked by its cam tn force downwardly thehold-down hard upon the shoe sole and clamp the last, the spring 88 willyield when the hold-down meets a greater resistance than the strength ofthe spring and the tail-piece will be turned until the shoulder 90 onthe cap engages the shoulder on the rod and the lever will then act as arigid bar to positively force the hold-down downwardly. During thelasting operation, the wipers are forced over the edge of the shoe soleupon the last and press the last downwardly against the tension of thejack spring 65. The spring 88 in compression between the tail-piece andrear end of the lever, causes the hold-down to follow up the last as itis forced downwardly by the wipers, and thus firmly holds the last inplace en the-jack against the thrust of the wipers. By turning the handwheel 84, the collar 86 is raised or lowered and the tail-piece adjustedrelatively to the lever 74 to change the position to which the holddownwill be lowered, and to provide for lasts of different sizes or changesin the kinds of shoes operated upon.

The hold-down 72 is pivotally attached to the post 73 by providing a earsegment. 96 on the foot and pivoting t e segment between downwardlyextending ears 97 on the post. A worm 98 mounted in bearings in the postand in engagement with the gear segment is adapted to be turned vto movethe segment and tilt the holddown in the direction of its length. Inlasting certain styles of shoes, a heavy-clamping pressure is requiredadjacent to the point or end of the sole, while other styles require a,heavy pressure at a distance from the point, and thus by tilting theholddown by means of the worm, the pressure may be brou ht at thedesired point. In placing the last 1n the machine, the holddown assistsin properly locating and positioning the same, serving as a rest againstwhich the shoe sole on the last is placed and a guide to give the properinclination to the last.

Secured within a transverse opening in the holddown 72 is a spindle 132which is screw threaded at its ends to receive two milled thumb nuts orheads 133 which may be adjusted toward and from the sides of the foot byturning the same. The lower edges of these heads lie close to the uppersurface of the Sole of the shoe on the last when the last is clampedbetween the holddown and jack and they serve as stop members to limitthe movement of the wiper plates over the edges of the sole, said stopmembers being adjusted outwardly into engagement with the inner sides ofthe upstanding lip of the insole, as shown in Figs. 131-l and 15 when ashoe having such a sole is being lasted.

When the machine is used to last the toe portion of a shoe, the lastupon which the shoe is secured is clamped between the head 60 of thejack and the holddown 72, and to guard against any possibility of thelast being displaced hy the wipers as they are forced forward and overthe shoe sole, a heel member 99 is carried by a swinging bracket 100pivotally attached to forwardly extending ears 101 on the forward end ofthe rocklever 74. This heel member comprises a downwardly extendingblade or seat portion curved to conform substantially to the form of theend of the heel portion of a last and a shank 102 extending upwardlyfrom the blades. The bracket for supporting the heel member comprises asocket or eye on the end of a longitudinally extending rod 103 toreceive the shank 102 and in which eye it is adjustably secured by a.thumb screw 104, said rod being likewise adjustably held by a thumbscrew 105 in a bearing or socket on the lower end of a two-part postwhich is pivotally supported at its upper end between the ears 101 by apivot rod 106 to which it is secured. The upper member 107 of the twopart post is formed with an axial bore to receive a stud bolt 108 on thelower member 109, and a coiled spring 110 sleeved upon the upper end ofthe bolt is put under compression between the upper end of the uppermember 107 and a nut or head 111 upon the screwthrcaded upper end of thebolt, which nut may be turned upon the bolt to adjust the tension of thespring. The spring thus holds the adjacent ends of the two parts of thepost in frictional contact and the heel member 99 may be swung laterallyintovposition to en the heel of a. last, the lower member o t e postturnin upon the upper member.

ecured upon one end of the pivot rod 106 is a rearwardly extending arm112 and a coiled spring 113 on the opposite end of said rod normallyholds the rod turned with the bracket 100 swung upwardly and forwardlyin position to permit the insertion of a last in the machine, and alsonormally holds the arm 112 in contact with the up er edge of the sidearm 114 of the lever 4. To turn the bracket 100 and lock the same withthe heel member in engagement with the heel of a last, a flan d roller115 is arranged to run beneath t e arm 112 upon the side arm 114, saidroller acting as a wedge to lift the arm, swinging and pressing the heelmember firmly against the heel of the last and locking the same inengagement therewith. The roller is journaled within the forked end of abar 116 which is pivotally attached at. its rear end to a lever 117secured at its lower end to a stub shaft 118 journaled in a bearing uponthe frame 3 and extending therethrough. To the inner end of said shaftis secured a rearwardly extending lever 119 carrying a roller 120 at itsrear end to engage a cam wheel 121 on the cam shaft 6. A coiled spring122 (Fig. 3) sleeved upon the outer end of the shaft 118 holds thelevers turned with the roll in contact with its cam, and a dat spring123 (Figs. 2 and 3) secured at one end to the u per end of the lever 117en ges the bar 16 at its free end to hold the roller 115 down upon thearm 114 which forms a track therefor.

In placing a last with a shoe thereon in position for lasting, theoperator will turn the bracket 100 by hand to bring the heel member intoproper engagement with the heel of the shoe, and the cam wheel 121 willthen at the proper time permit the spring 122 to turn the levers andmove the roller 115 beneath the raised end of the..bracket arm 112. Thesp thus operates to move the roller beneath tEe lever and positively tolock the heel member in the position to which it is turned by theoperator, said roller also operating as a wed e to turn the bracket andforce the heel mem er firmly against the shoe heel where it is heldlocked until the cam 121 turns the levers against the action of saidspring and retracts the roll from beneath the bracket arm.

To hold the edge of the sole of a shoe at its end, down upon the lastagainst being wiped up and turned back by the wipers during the lastingoperation, a presser-finger 124 is provided. This presser-fingercomprises a member having a thin lower edge to engage the shoe soleclose to its edge at the extreme end of the last, said edge being curvedto conform to the outline of the sole, and also provided with a socketin its upper end to receive the lower end of a post 125 adjustably andpivotally attached to the forward end of an arm 126 which is pivotallymounted intermediate its ends to turn upon a transverse shaft 127 ixedin suitable vbearings therefor on the frames 3. The rear end of the arm126 is provided with a roller 128 to ge a cam wheel 129 secured upon thecam s aft 6 and operating to rock the bar and raise and lower thepresser linger in timed relation to the movement of the wipers. The armis held turned with its roller in engagement with the cam by a coiledspring 130 (Fig. 2) secured at its lower end to a cross-bar on theframes 3 and at its upper end to a bar 131 secured to and forming anextension of the rocker-bar.

The forward end of the arm 126 is forked and provided with bearings forlaterally extending trunnions 134 (see Figs. 2, 3 and 16) on the head135 of-a lever 136 adapted to turn upon said trunnions within the forkedend of the rocker-bar. The head 135 is formed with a vertical bore whichis en larged and formed square in cross-section at its lower end andinternally screwthreaded at its up er end to receive a screwthreadedsleeve 13 (Fig. 16) on a reduced upper end of the post 125', held inplace to turn freely thereon between a collar 138 on the upper end .ofthe post and a collar 139 fixed on the post Within the enlarged lowerend of the bore of the head. The collar 139 forms a guide for the postwithin the head to prevent the post from turning therein and said ost israised or'lowered relative to the hea by turning the sleeve 137, a quickvertical adjustment being thus provided for the presserfinger. Themember 124 is made quickly detachable from the post by providing a flatspring 140 secured at one end to the post and carrying a pin 141 at itslower end to engage an opening in the socket end of the member and acorresponding openin in the post. The member may thus be quie lydetached and another having a different form put in its place when thereis a radical change in the shape of the shoes being lasted. The lever136 is adjusted to swing the presser linger and locate the member 124 inproper relation to the presser foot 72 and is yieldingly held in .itsadjusted position by a rod 142 pivotally attached at its lower end tothe arm 126 and having a 'screwthreaded end extending upward through anopenin in the end of the lever where it is provideil with a thumb nut143 engaging the upper side of the lever. A coiled s ring 144 is sleevedon said rod between the lever 136 and the arm 126 to normally hold thelever against the nut 143 which may be turned ou the rod to swing thelever on its trunnious and adjust the presser-finger toward or from thepresser-foot. If in the operation of lasting a shoe, the wipers shouldstrike the sole engaging member, it will be swung forwardly thereby, itscarrying lever 136 turning against the action of the spring 144.

' To stretch the shoe up r up around the toe or heel of a last an spreadthe same during the lasting operation, a series of Iplincers 145 areprovided, each comprising a xed jaw 146 having a vertically extendingshank portion 147 secured at its upper end within an opening in acarrying bar 148, and movable u wardly therethrough to a limited extent,t 1ere being two of these carrving bars, one at each side and aconsiderable distance above the wipers to carry all of the pincers atthat side. lach of the pincel-s further comprises a movable jaw 149which is pivotally attached at. its upper end to a collar 150 free toslide upon the shank 147 and is carried by a lever 151 pivotallyattached at one end to the movable jaw intermediate the ends of saidjaw. said lever being pivotally secured intermediate its ends 154 and tothe fixed jaw to turn thereon and raise and lower the movable jaw. A rod152 is pivotally connected at its lower end to the outer end of eachlever 151 and this rod extends freely u ward through an opening in anactuating r 153 and is screwthreaded at its upper end to receive a thumbnut 154. Sleeved u n each rod 152 between said nut e upper side of thebar 153 is a coiled spring 155 and a collar 156 fixed ou said rod belowsaid bar limits the upward movement of the rod through the bar. Anupward movement of the bar 153 relative to the bar 148 will turn thelever 151 and will swing and slide the movable jaw downwardly intoclamping position to clamp the rojecting upper edge of the shoe uppertween its laterally extended lower end which has a gripping face, and asimilar lower end on the fixed jaw. By attaching the movable jaw to thefixed jaw by means of the sliding collar 150, the movable jaw may becarried bodily upward by the lever 151 and at the same time swung awayfrom the fixed jaw to receive the edge of the shoe upper. A wide openingbetween the jaws is thus secured with but a comparatively short swing ofthe movable jaw and the said jaws may grip the shoe upper well down atthe side of and close to the last without the movable jaw stri Y theedge of the last or shoe sole in closing. By providing the springs 155,the jaws are yieldingly closed and the gripping force of the jaws isdetermined by the tension of said springs which tension may be readilychanged by turning the thumb nuts 154 and regulated so that the upperwill be held with just sufficient force to stretch the same up aroundthe last and so that it will be gradually pulled from between the jawswithout injur to the leather as the last is lowered to strete and updrawthe leather and also as the wipers force it over and down upon the edgeof the shoe sole as later explained.

Upon the fixed jaw of the forward pincers (Fig. 12) at each side of thelast, is a downwardly extending lug forming a support for a roller 157adapted to engage the side of the shoe upper upon the last at a distancebelow the sole and to thus form a guide for locating the pincers aboutthe last in position to receive and grip the shoe upper, the carryingbars 148 being pivotally Supported at 158 to turn inwardly toward thesides of the last and bring said rollers into engagement with the sidthereof after the last with a shoe thereon has been secured in positionfor lasting by the jack and presser foot. The carrying bars are extendedrearwardly beyond t eir pivotal rearwardly extending ends are pivotallyattached links 159 pivotally connected together at their opposite endson the forward end of a bar 160 which in turn is connected at itsdipport, and to these rear end by a ball and socket joint to the upperend of a bell crank lever 161 pivoted at 162 to the frame and providedat the end of its rearwardly extending arm with a roller 163 to engagethe riphery of a cam wheel 164 secured upon t e cam shaft 6. A. flatspring 165 shown in Fig. 2, is secured to the table 2 and presses upwardon the rearwardly extending arm of the lever 161 to hold the roller 163in contact with its cam and to yieldingly swing, through the medium ofthe bar 160 and links 159, the carrying bars toward the sides of thelast and yieldingly hold the rolls 157 against the side of the last. Theuniversal joint connection between the upper end of the lever 161 andthe bar 160, and the link connection of the forward end of said bar tothe rear ends of the carrying bars, permits of the free turning of saidcarrying bars independently of each other and the accurate adjustment ofthe pincers to the work, the closing ressure of the spring 165 beingalso equahzed between said bars to hold the pincers at each side of thelast pressed toward the shoe with egual force. The described pincermechamsm, per se, forms the subject-matter of a divisional application,Serial No. 200,607, filed November 6, 1917.

A rock arm 166 is mounted intermediate its ends to turn freely upon thefixed shaft 127 and to the forward laterally enlarged end of this armare pivoted at 167 (Fi 3 and 8) the rear ends of the actuating ars 153to turn on said pivots with the carrying bars 148 and to be raised andlowered by said member when the same is rocked on the shaft 127 by acoiled s ring 168, shown in Fig. 3, attached at its ower end to a crossbar on the frame, and at its upper end to a bar 169 secured to andforming a rearward extension of the rocker, the rocking movement of saidmember and the. consequent opening and closin of the jaws of the pmcers,being contro led by a cam wheel 17 0 on the cam shaft 6 upon which camrides a roller 171 on the rear end of the rocker member. The pincers arethus actuated by the cam wheel 170 in timed relation to the movementofthe Wipers to grip the edge ofthe shoe upper and to stretch 1t uparound the last.

A pivoted or horizontally swinging suprt is provided for each of thecarrying ars 148 comprising a member 172 pivotally supported at 173 uponbearings provided therefor upon the upper side of the bracket 21 (Fig.1), the pivots 158. upon which said bars 148 turn, bein located 1n theforward ends of said mem rs. Each member is formed with an integral gearsegment 174 (see Figs. 8, 10 and 11) meshing with the segment on theother member so that said members are caused to turn together inopposite directions, and one of the members is formed with a laterallyextending arm 175 to the outer end of which a rod 176 is attached by auniversal joint connection, the rear end of said rod being pivotallyattached to the upper end of a bell crank .177 pivoted upon a stub-shaft178 (Fig. 1) having a bearing in the frame 3 and provided at its rearend with a roller 179 to engage a camwheel 180 secured upon the camShaft 6. A spring 181 (see Fig. 1) coiled upon the outer `projecting endof the stub-shaft 178 engages beneath the rearwardly extending arm ofthe lever 177 and exerts a force to hold said roller 179 in contact withsaid cam. Said lever is thus ositively actuated by the cam 180 to turn te supporting members 172 a determinate distance upon their pivots 173and in order that the carrying bars 148 may be moved bodily with saidsupporting members about the axes of said ivots, to swing the pincers ateach side of t e last laterall away from the last and in a directionwhic is substantially radial to the end of the last, the bars 148 areautomatically locked to their supporting members 172 to turn therewith,bv forming each member with an integral ratchet 182 adapted to beengaged by' a pawl 183 having a segmental face to engage and lock withthe ratchet. Each pawl is pivoted between laterally extending ears onthe carrying bars 148 upon pivot pins 184 and is normally held inengagement with its ratchet by a spring 185 coiled at its ends aroundthe pivot pin and engaging the pawl intermediate its ends. An upwardlyextending tail piece 186 on each pawl'is adapted to be engaged by theactuating bar 153 (Fig. 10) when the Same descends to open the jaws ofthe pincers. As soon as the cam 170 operates to rock the rocker member166 and raise the bars 153 to close the jaws upon the work, the pawls183 are released and come into engagement with their ratchets,thuslocking the carrying bars to the pivoted supporting members 172 toturn therewith and holding the same locked until the actuating bars areagain lowered at the end of the lasting operation to open the jaws forthe reception of another shoe.

The incers are automatically adjusted relative y to the sides of thelast to osition themselves to engage the edge of t e shoe upperprojecting above the insole by the initial inward swinging movement ofthe carr ing bars 148, the spring 165, (Fig. 2) hol ing these bars withthe rollers 157 in contact with the sides of the shoe. After the closingof the pincers upon the stock and during the lasting operation, thepincers are moved bodii and laterally away from the opposite si es ofthe last in divergent directions from the median line of the end of theshoe, or, in other words, are moved diagonally outwardly and forwardlyin the direction of the end of the shoe with their jaws gripping theedge of the shoe upper to spread and stretch the leather and eliminateall wrinkles. The danger of spreading and stretching the upper of a shoehaving a narrow heel or toe, too milch, and of not stretching the stockon a broad heel or toe far enough to eliminate the wrinkles, is thusobviated as the pincers are first adjusted to the particular shoe beinglasted and then moved by a separate cam a Vdeterminate distance everytime to subject the shoe upper to the same spreading and stretchingaction regardless of the size or shape of the heel or toe. The directionof outward movement of the pincers is important, particularly in lastintoes, since by outward pull along lines iagonally forward toward the endoi the last, the up r is centered on the toe and is uniform y tensionedso that the wipers can exert uniformV molding pressure on the tensionedupper.

When the machine is in open position to receive a lastwith a boot orshoe upper in place thereon for lasting as shown in Fig. 1, the jackcani is at the extreme lower end of its movement, the roller 69 being incontact with the innermost run of the jack cam, as shown in Fig. 28; thehold-down is raised to the limit of its movement, the roller 79 beingin' contact with the inner run of the cam 80, as shown in Fig. 29; thepresser .nger is also fully raised, the roller 128 engaging the innerrun of the cam 129, as shown in Fig. 26; and the heel member is swungupwardly, its locking roller 115 being moved rearwardly by theengagement of the roller 120 with the high art of the cam 121, as shownin Fig. 21.

ith the parts in these positions, the operator may insert a last with ashoe upper in place thereon for lasting, by placing the sole against thehold-down with the toe portion adjacent to or against the formed edgesof the wiper plates which are held moved rearwardly by the engagement ofthe roller 25 with the inner run of the cam groove in cam 26, and alsoheld in open position by the engagement of the roller 54 with the innerrun of the cam groove in cam 55, as shown in Figs. 24 and 25. When thelast is so placed, the upstanding edge of the shoe upper will rojectbetween the jaws of the pincers which) are held open by the spring 168acting on the rocker bar 166 to hold the roller 171 in contact with thecam 170, as shown in Fig. 23 and the actuating bar 153 in loweredposition.

The operator will then swing the bracket 100 by placin his hand thereon,to bring the heel mem er 99 into enga ement with the shoe heel on thelast. e will then start the machine by placing his foot upon a treadle,or other means for movingr the bar 10 and throwing the clutch 8 intoenont with the driving pulley. By the movement imparted to the cam shaft6, or during the turning of the cams from starting ition indicated at a,in Figs. 21 to 29 inc usive, to b, the jack is raised and the presserfoot is simultaneously lowered to clamp the last between them. Thelocking roller 115 is at the same time moved forwardly to lock the heelmember in sition and the cam 164 is turned, permittlng the spring 165 toact upon the lever 161 and close the carrying bars inward, adjusting thepincers to the sides of the last. The cam 170 is so set in relation tocam 164 that immediately upon the engagement of the roller 157 on thepincers with the sides of the last, said cam will operate to cause theactuating bars 153 to be raised and close the jaws of the pincers uponthe upstanding edge of the Shoe upper and firmly grip and tension thesame. Y

During the further turning of the cams from position b to position e thecam 129- operates to lower the presser linger into engagement with theshoe sole on the last at its toe portion outside of the lip of the sole,and cams 26 and 55 operate respectively to move the wipers forward intoengagement with the shoe upper some distance below the sole of the lastand to close said wipers around the toe.` When the shaft is turned toposition c, the roller stud 18 will drop into the second notch in thestop plate '16 provided the bar 10 is not held down by the operator, andthe machine will be automatically stopped to give the operator anopportunity to examine the work. In turning from position b, the roller25 moves into a portion of the cam slot which is Wider than the diameterof the roller givingsaid roller horizontal play therein, and the wipersare thus yieldingly engaged with the point of the toe and if theoperator in placing the last in the machine should position it upon thejack too close to the wipers to permit their full forward movementwithout moving the last upon the jack, the spring 27 will yield and thusprevent injury to the shoe. Variations in the thickness of the leatheris also provided for by the yielding forward movement of the wipers andthe yieldin closing movement secured by means of tie springs 45 and 49provides for variations in the thickness of the leather at the sides ofthe toe and lasts of different. swings or shapes. By turning the screws39 either or both of the wiper plates may be adjusted to conform tolasts of different swings and sizes.

The enlargement in the width of the cam slot is important in that itpermits the wipels bodily to be displaced rearwardly by the incline ofthe toe end during upwiping movement so that the roll 25 is spaced fromthe controlling edge of the cam slot when the plane of the sole isreached in the n wiping movement. When this point is reached the spring27 will instantly impel the wipers over the edge of the soleindependently of their operating member or controlling cam.Simultaneously, the yielding springs 45 and 49 in the wiper closingmeans, which have been compressed in closing the wipers against thesides of the toe preparatory to and during the upwipe, will instantlysnap or impel the Wipers over the sides of the toe end of the soleindependently of and without waiting for their nonvielding actuator,-thecam 55--, to act. This provision is advantageous in that it enablestighter toe lasting to be accomplshed than would be obtained if thewipers waited to close, as they do in all prior machines known to me,until they have been raised to a predetermined level. This springimpelled movement of the wipers over the edge of the sole independentlyof their actuating'or operating means can not injure the sewing rib ofthe sole since the stop members 133 back up the sewing rib at the sidesof the toe. In some cases it may be desirable to back up the sewing ribat the end of the toe and in such cases the nut 143 (Fi 16) can beadjusted to move the presser nger from a position just outside the ribto a position inside of and against the rib. Ordinarily, the positivelimitation of forward closing over movement aiforded by the controllingedge of cam 26 will have the described function but the operator may,obviously, utilize the presser linger as described.

During the turning of the jack cam 70 from position c to g, the jack isgradually lowered and the hold-down is correspondingly lowered by itscam 80 to force the last wlth the shoe thereon downward and to cause thewipers to wipe the upper up around and slightly over the bottom of thetoe of the last, the edge of the u per being held during this movementby t e pincers, to stretch the leather during the wiping up so that theupper is more closely conformed to the last. On the upwiping movement,the convexity of the end of the last may be such that the wipers mustyield lengthwise to avoid injury, by scraping, to the upper and thelengthwise bodily yielding movement of the wipers is therefore advantansin this case also. The presser linger nring the turning of its cam fromc to g is lowered in proportion to the downward movement of the last, tohold it down upon the shoe sole and hold the edge of the sole downirmljs,1 upon the last to prevent said edge from bein wiped up andturned back by the wiper p ates when said wipers wipe up the upper belowthe sole on the last and are projected quickly over the edge of the solewhen the plane is reached in which the wipers can advance, by thecompressed spring 27, as previouslx)r explained. Simultaneously a quick,closin movementI i s 1inparted to the wipers y the tensioned springs 45,49, the cani groove of cam 55 heilig formed concentric from c to to holdthe wipers closed under spring tension upon the shoe toe durin Y thewiping up of the toe, and from fl to being operative to close the,wipers partly over the sole edge.

During the turning of the cams 26 and 55 from to g, the wipers areretracted and opened out and remain in that .position during the turningfrom 'r/ to a point between li. and i'. Coineidently with the retraetingmovement of the wipers a rise in holddown cam 80 (see, Fig. 29) causesthe liolddown to press downwardly the last and pick, reliev ing thepressure of the jack spring against the retracting wipers. \Vhen thewipers ha ve so moved away from engagement with the Shoe, the jack andpresser foot are raised during the turning of the cams from i to i sothat when said wipers are again moved forward and closed during theturning of the cams 26 and 55 from midway between h and i to the pointz', said wipers will again engage the shoe upper below the shoe sole andwill operate to wipe the shoe upper up around the toe of the last asecond time during the second lowering of the jack and hold-down astheir cams are turned from a'. to n. The presser finger is raised at i,with the second raising of the last and is gradually lowered with thejack during the turning to position Z when itv is quickly raised to itsoriginal or open position of the machine to get out of the path of thewipers as they are forced over the edges of the sole and stopped by thestop members 133 from wiping inward over the upstandiiig lip of theinsole. The turning of the cams from position n to a rcturns all of theparts to their original or open position for the insertion of a secondlast. During the second advance of the wipers over the edge of theinsole and their retraction, the jack spring and liolddown are effectiveto exert compacting pressure against the advancing wipers and to relievesaid pressure when the wipers retract, as described in connection withthe first wiping operation. By this arrangement the shoe upper issubjected to two wiping operations dnring the cycle of operation. itsupwardly projecting edge being gripped and held by the pincers tostretch the leather. until the tinal inward movement of the wipers overthe edges of the shoe sole.

The cam 180 for turning the carrying members 172 and moving the pincersbodily away from the Sides of the last to spread and stretch the shoeupper, remains inoperative during its turning from o: to d with thepincers gripping the edge of the upper. As the wipers start to moveforwardly and close over the bottom of the last, said cam operates tomove the pincers laterally away from the sides of the shoe, with theirjaws gripping the edge of the upper, and thus stretch and spread the.leather as it is wiped over and down upon the edge of the sole. Thepinceis are held in the position to which they are turned, during `theremainder of the lasting operation or until the wipers again start tomove forwardly and close over the edge of the sole, when the cam willpermit the carrying members to swing inwardly and cam 170 will operateto open the pincer jaws. Preferably, and substantially as indicated bythe cani slots, Figs. 25, 27, 28 and `29, the grippers will begin toswing laterally, inward toward the side of the last and shoe.subsequently to the point (l, Fig. 29) when the last and jack reach thelimitof lowering upwiping movement. so that the wipers will mold theupper to the toe ot' the last, and over the ridge between the toe andlast bottom while the upper is stretched and under tension. Between thepoints l and m the wipers begin their advance over the edge of theinsole, forcing the edge of the upper downwardly on the insole, againstthe upward compacting pressure of the jack spring and. as they Areachfully closed position (o, Fig. 25). forcing the upper firmly and closelyinto the corner. between the feather (or bottom) and lip of the insole.As the wipers begin their advance over the edge of the insole, thegripper cani (Fig. 27) swings the grippers laterally inward toward theside of the shoe and the clamping cani (Fig. 23) coincidently operatesthe grippers to relieve the grip on the upper. The indraw or tension onthe upper. as the wipers reach the ridge between the side of the toe andthe last bot toni just before the grippers swing inwardly and release,causes a heavy tension to be cxerted against the upper which is electivcto mold the upper tightly and closely over the ridge. and which does nottear the upper since the spring clamping pressure of the grippers willpermit the grippers to yield and allow the wipers partially to pull theupper from between the, gripping jaws as the wipers advance over theridge. The inward swinging and releasing movement of the grippers.thcrefoie, occurs after the wipers have molded the upper to the last andhave clamped it over the edge of the insole. (lonscquently. there is nopossibility of slack occurring in the tension of the upper while it isbeing molded and conformed to the last.

Between the points g and k the jack cam is formed with a slightdepression and the hold-down cam S0 with a corres onding projection sothat the jack and ho d-dowii will be lowered slightly just at the end ofthe first wiping operation to permit a se-
